The installer includes an "upgrade" function, we strongly urge you to install from scratch though since updating is known to break sometimes. It is simply next to impossible to determine what people have installed and how it affects the system.

Why would it suddenly work on a 68k platform?

Good questions for 68k? well, I hope that the project NatAmi as they spoke in the interview in the las issue of Amiga Future, will can plug or connect instead of one 68040-60 a PPC CPU, and we will can enjoy the two worlds without emulations, software 68K and PPC.
And for the Efikas? because I have one, but I'll like can enjoy the OS 4.1 instead of the other official alternatives....

This is fantastic news.

While I am happy to see development continue on OS4, there needs to be substantially more to it than some eye-candy improvements before I will be convinced to spend over 100 euro (more so for those of us in the USA) for an OS upgrade. According to Hyperion's webpage, 9-10 of 15 improvements (60%) are graphics/GUI related. I'd need to have more specific info on the vague Quote:

substantial new functionality which is a prerequisite for the deployment of industry standard applications

and Quote:

much, much more

before I ante up.

Do we get new/more device drivers, datatypes, filesystems, a modern HTML engine, a Java VM, improved multi-boot UBoot? Stuff a modern OS brings to the table. Is this equivalent to going from Win95 to XP or Mac OS9 to OSX? Yes, those are more expensive, but it is not like there is a huge OS4 market and they include more features / capabilities out of the box. What makes this level of upgrade any different than the OS4.0 updates in terms of improvements or added capabilities? In other words, convince me I should pay for it, other than "that's the way it is, pay up or shut up". Is there somewhere I can go on the web to get more details (no local dealer where I live)?

Why the cautionary cloud? Amigans got burned with the OS3.5 to 3.9 ripoff (had to pay for 3.9 features promised in 3.5). And the less than promised A1-XE. I am not saying that has been my OS4 experience. I have been happy with that experience so far. BTW, I have an XE running OS4.0, I am not a blue vs. red troll here. Just convince me this upgrade is worth more of my money.

Incidentally, will there be a non-boxed, CD only version available? With the Quote:

Powerful and user-friendly installation utility

what do I need a printed install document for?

Hmmm, I'm sure I'm reading too much into this but I find it interesting that Rogue denied that it works for the NatAmi but convieniently left out the Efika and Sam440 part of the original message.

Now... what about the MacMini

@DL

I count 8 graphics-related items in the list. Let's go through a few of the ones that are not just eye-candy.

Quote:

# Hardware compositing engine (Radeon R1xx and R2xx family)

At first this sounds like pure eye-candy. However, many programs (games in particular) require this in order to run at a decent speed. I hope that SDL has been improved to use these features. This makes more games worth porting.

Quote:

Implementation of the "Cairo" device-independent 2D rendering library

This is a pretty good cross-platform library for 2D graphics, and apps such as Firefox 3 use it. Don't expect a Firefox 3 port any time soon, but this increases the likelihood that apps requiring Cairo will be ported.

Quote:

# Reworked Warp3D Radeon drivers with new functionality # Improved OpenGL support through MiniGL 2.0

I'm lumping these two together because they are related. Improved OpenGL support means that more OpenGL apps/games can be ported over. We may actually see a fully usable Blender port.

So, you see that not all the graphics related stuff is just eye-candy. I'm also interested to see what the "much much more" includes.

Great !

Hoping this is, finally, the starting point to going forward again for AmigaOS...

Now... SAM, MAC MINI, Apple PPC laptops and, who know ? The world !!!

Almost wish Amiga OS had a register now eh?

Yes it is possible to "update" a 4.0 installation.

HOWEVER, I would personally and highly recommend you do a clean install of OS 4.1 on a freshly formatted partition.

And, before you do anything, it would be wise to have a backup of all of your data, just in case. I am speaking generally here about any operating system and computer....having a current backup is very important.

I would recommend that for technical support and troubleshooting it will be best for you to start clean on a formatted partition...

There's absolutely no reason for a huge bloated single-file "registry" implementation in any OS, let alone AmigaOS. Well, unless you have a sucky filing system like FAT32, where every small file takes-up a whole cluster...

AmigaOS's Env: & EnvArc: are quite sufficient for most "registry" purposes. But it's use could certainly do with expanding, to handle tracking of what has been installed where, and what other things depend on other things. (Epoc/Symbian has a very elegant (un)installation system, with no registry in sight, although EnvArc might not be an appropriate place to store those kinds of files.)

A new BIOS update for A1 was necessary to OS4.1?
Maybe an update price from OS4.0?
Tnx and bye!

Why do people keep asking if there is an upgrade price for OS4 owners. How many people have an A1 without OS4?

@Rogue

Since this is a touchy subject, let me start off by saying that my intention is not to troll, this is a genuine question. Now that's out of the way...

The NatAmi hardware developers have said that because of the extremely low memory latencies on the NatAmi design (and the slow memory controller on AmigaOnes), they expect performance of their board to be on a par with that of an AmigaOne board. The AmigaOne is currently the fastest Amiga hardware in existence, and companies that make hardware that could potentially run AmigaOS 4 are (for obvious reasons of cost and business risk) using SoC based designs that are slower than AmigaOnes. So if the NatAmi team is correct, their system will be the fastest Amiga, that can be bought new, for the foreseeable future.

Given that, if hard benchmarks do confirm the performance advantage of NatAmi over PPC Amigas that can be bought new, do you think that Hyperion would reconsider it's "PPC only" stance? (standard disclaimers apply, I'm asking you as an engineer and someone who knows the thinking process of the decision makers, not as an official spokesperson)

I'm sure, Hyperion do already have a 68k OS4 running in their offices...
Also they already must have a x86 version of OS4 running somewhere Just to be safe...

@CodeSmith

Do you really think that a 90MHz 060 with what, DDR400 RAM? (more likely DDR266) and 8 or 16kB cache, would outperform an 800MHz+ G4 with SDRAM133 and 256 or 512kB cache??! Hardly.

A 50MHz 060 can do about 170MB/s to/from its L1 cache IIRC. Let's pretend it can do this to the RAM, which is very unlikely no matter how fast it is, then it would do something like 306MB/s@90MHz which indeed is faster than the A1s 230MB/s with tweaked Articia, but I still feel it very unlikely that it would outperform the A1 even if you disable all caches in the G4 and makes it rely on its slow RAM.

Besides SAM440 (533MHz) also has DDR directly connected to the SoC CPU most likely giving very low latency aswell and makes it faster than an 800MHz A1 on average usage. The A1 will only beat it at pure CPU power on algorithms that fits in the cache.

We're actually thinking about something like a registry.

A single-file database is, in general, too vulnerable to damage. ENV: and ENVARC:, however, are seriously misused for too many purposes that it was never meant to be.

There are some things that would be well served with a configuration database, for example device drivers installed and their relation to hardware. As I said, it is currently under consideration.
